The MAX5901ACEUT+T is a Hot Swap controller that offers a secure solution for the connection and disconnection of high-power supplies without causing disruptions to the system. It features a wide input voltage range of 4.5 to 40V, and a low operating current of less than 170mW. Moreover, its high-efficiency power supply design and intellirouteTM circuit reduces system heat, saving valuable board space.

The MAX5901ACEUT+T is suitable for a wide range of applications, including Industrial Automation, Automotive, Instrumentation, Medical Devices, IoT and Surveillance. It is ideal for protecting high-power circuits, providing low on-resistance, high load current capacity, current-limiting and thermal protection. Additionally, its built-in Overcurrent Protection (OCP) prevents overcurrent loading and external component failure, while its Overvoltage Protection (OVP) prevents reverse voltage connection and damage to the load.

The working principle of the MAX5901ACEUT+T is designed with an internal Power MOSFET switch that operates at a rate determined by the overvoltage and overcurrent circuitry, thus providing the hot-swap operation. When the desired output voltage is detected, the hot-swap control circuitry activates the internal switch and powers the load. The current limiting feature of the circuit allows a maximum current threshold, beyond which power is disconnected automatically, thus protecting the system.

The MAX5901ACEUT+T is an efficient and robust Hot-Swap controller that is based on Ultra-Low Dropout (ULD) architecture and is particularly suitable for systems that may require dynamic power changes. Its superior design reduces power consumption and extends system lifetime in sophisticated high-power applications.
